I filed taxes says accepted but no processed status is action needed see I am getting a letter about non filer status anny one know what this means?

Once your return is filed, TurboTax has no control over the processing of your return or the release of your refund.

 

Due to PATH Act, the IRS holds refunds for EITC/ACTC customers until March 3.  

 

Here are a couple FAQs to track your refund:
When will I get my federal tax refund?
How do I track my state refund?
Why does Where's My Refund say "approved" but TurboTax still says "accepted"?

 

Why do some refunds take longer than others?

What if my IRS refund is taking longer than 21 days?
